Abstract:
Present disclosure provides a portable viscometer including a body and a measuring unit disposed on one side of the body. The measuring unit includes a capillary tube detachably attached to the measuring unit, and a first sensor and a second sensor, the first and second sensors being disposed adjacent to the capillary tube and vertically spaced apart from each other, and the capillary tube includes a bead therein. The bead may be fixed on the inner surface of the capillary tube by a fixing compound which is soluble in a fluid to be measured.
Abstract:
Provided herein is an apparatus for measuring properties of a fluid, the apparatus including: a light emitting unit configured to emit a first light having a first wavelength and a second light having a second wavelength that is longer than the first wavelength, from outside a fluid accommodating unit where the fluid flows in and out to a measurement area inside the fluid accommodating unit; a light receiving unit disposed outside the fluid accommodating unit and configured to receive the first light and second light that passed the measurement area; and a measuring unit configured to measure the properties of the fluid based on an intensity of the first light and second light that the light emitting unit emitted and an intensity of the first light and second light that the light receiving unit received.
